ASoC: DPCM: make some DPCM API calls non static for compressed usage
The ASoC compressed code needs to call the internal DPCM APIs in order to dynamically route compressed data to different DAIs. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com> Signed-off-by: Mark Brown <broonie@linaro.org> (cherry picked from commit 23607025303af6e84bc2cd4cabe89c21f6a22a3f) Signed-off-by: Mark Brown <broonie@linaro.org>
